What would it be like to live for 100 years or more?

Megan Alexander may be about to find out. She is lucky enough to have been born in one of the handful of places where life expectancy for girls is 100 years or more, according to new figures from Public Health England.

Megan was born seven months ago on the Northburn Estate in Cramlington, Northumberland, which has the highest life expectancy for girls in the country, at a staggering 105.

The average is rising, so that within Megan's lifetime it may be that most girls in England will be expected to reach their centenary. Boys are lagging behind though - their highest is just 98 years, in privileged Knightsbridge in London.

But what kind of life can Megan expect to live? How will the world have changed by the time she reaches her centenary?
